There was a new card teased a season ago that Seth said would bring a whole new archetype , please don’t introduce more legendaries that are impossible to level.(besides you know the 15 fisherman they gave us last season on trophy road) but it’s been months since there was a new common released

We do have plans to release more Common cards! Interestingly enough, Commons tend to the be the hardest cards to design. We generally want Commons to be very mechanics-light, easy to understand. With most of the basic cards already designed (Knight, Barbarians, Goblins, etc) its difficult to come up with new cards, with few mechanics, that don't overlap with existing cards. Sure, we COULD make another mini-tank with no special abilities that happens to cost 4, but that feels really cheap on our part compared to something with a lot of new stuff. Having a lot of new mechanics, however, naturally drifts a card to Epic or Legendary.

If I could go back in time, I think cards like Mega Minion and even PEKKA would make more sense as Commons, whereas cards like Tesla or Skeleton Barrel should probably be Rares or higher. But we are challenging ourselves to think of more Common/Rare type cards, and I don't think you'll have to wait too terribly long for a non-Legendary release :)
